A joint House-Senate committee is beginning the work of developing a storm disaster aid package that Minnesota lawmakers will consider in an emergency session next month. The group is convening tonight (WED) to help shape the proposal that is the only agenda item for the September 9th Special Session. Legislators are pulling together a state match for federal disaster assistance. Eighteen counties are in line for aid to recover from severe storms in June that caused widespread damage to infrastructure, homes and property. Sibley and McLeod Counties are among those eighteen. Two other counties could get state help for weather emergencies last winter as well. The working group convening tonight includes top finance committee lawmakers from the Minnesota House and Senate.
